摘　　要：针对斜齿轮啮合过程中,建立了考虑齿面摩擦的斜齿轮啮合副动力学模型。首先对斜齿轮副啮合进行齿面接触分析和加载齿面接触分析,得到齿面接触路径、接触位置法向位移,在此基础上计算了时变啮合刚度激励、齿面滑动摩擦系数和摩擦力臂。其次,建立并求解了考虑齿面摩擦的斜齿轮副动力学模型,计算了动态啮合力/速度/位移。由齿面上的滑动摩擦系数、摩擦力臂和动力学方程构成斜齿轮副啮合动力学耦合系统,通过解耦计算,对模型系统方程进行了求解。最后通过实例验证了该模型的有效性。Aiming at the meshing process of helical gears,a dynamic model of helical gear meshing pair considering tooth sur⁃face friction is established.Firstly,the tooth contact analysis and loaded tooth contact analysis of helical gear pair meshing are carried out,and the tooth contact path and normal displacement of contact position are obtained.On this basis,the time-varying meshing stiffness excitation,sliding friction coefficient of tooth surface and friction arm are calculated.Secondly,the dynamic model of helical gear pair considering tooth surface friction is established and solved,and the dynamic meshing force/velocity/dis⁃placement is calculated.The meshing dynamics coupling system of helical gear pair is composed of sliding friction coefficient,friction arm and dynamics equations on the tooth surface.The equations of the model system are solved through decoupling calcu⁃lation.Finally,the effectiveness of the model is verified by an example.
